I'm posting this because some people post their HijackThis logs without first using the already available, free tools to clean up their system. There are a lot of great tools out there to help get rid of what's hijacked you. The most popular and most commonly used are:

AdAware

and

Spybot Search & Destroy

Please download and run these both - they are the most essential.

Another one that comes into common usage is CoolWebShredder, if CoolWebSearch has taken over.

The final recommendation I have before posting your HijackThis log is to run a full virus scan with the latest definitions. The most commonly used online virus scan is probably Housecall, although there are many others - see the links to some of them in my sig.

Thank you!
